Process

LLW series screen worm centrifuge is the one with low energy consumption, stable performance and good separating effectiveness. The separation processing from feeding to dewatering, cleaning and discharging is continuous with high processing efficiency and high degree of automation.

♣Gearbox: mechanical gearbox and hydraulic gearbox, so as to suit for separation of different materials.

♣For materials with high concentration and poor mobility, LLW screen worm centrifuge with screw feeding device is more suitable.

Working Principles

The feed suspension is introduced to the centrifuge through a feed pipe and into the feed distribution chamber, and is jetted into the basket through the hole near the cone point of the conveyor. Under centrifugal force the solids filtrate from the liquid and settle against the basket wall, while the clarified liquid exits over the overflow screen. The solids in the conical basket are conveyed up from the smaller end to the bigger end while the conveyor turns at a slightly different speed. The bigger diameter is, the bigger centrifugal force produces to separate the liquid/solids. The solids are dried when they are drained out the basket.

Design Features

♦Main parts such as basket and conveyor are made of high-quality corrosion-resistant stainless steel and titanium alloy;

♦10°,15°and 20°available for basket angle depending on the process conditions;

- Basket angle 20°: this standard angle has been proven to be perfect for separating most of materials. No large pushing force is required from the conveyor because the solid phase slips from the small end to the large end with the increased centrifugal force.

- Basket angle 10°: when washing is required, the 10°basket angle is the first choice.

♦Special-purpose metallic screen with thickness up to 1.0mm, extending service life;

♦Variable-frequency control with stepless regulation basket rotating speed;

♦Feeding, filtration, washing, dewatering and discharging to be done continuously, offering large capacity;

♦Independent lubrication system with simple and reliable lubrication means but good cooling effects;

♦Safety protection: speed detection, over-vibration protection, motor overload and overheat protection, etc;

♦Reliable and stable hydraulic gearbox centrifuge is suitable for materials with high viscosity.

♦For materials with high concentration and poor mobility, LLW screen worm centrifuge with screw feeding device is more suitable.

Application

LLW screen worm centrifuge has been widely used in such industries as chemistry, food, salt, mining and pharmacy. Due to its separation principle and structural characteristics, it is mainly suitable for those materials with large particle size and without strict requirements on particles crushing.
